How FIT3178 is assessed
| Component | Weight | Format |
|---|---|---|
| Learning portfolio · hurdle | 100% | Competency-based portfolio with weekly pass tasks and OnTrack discussion |
The current FIT3178 structure is a 100% competency portfolio. Required pass tasks must meet the published standard and timing controls, with work discussed through OnTrack.
What FIT3178 covers
The path runs from Swift, State and the iOS Runtime through Maps, Location and Privacy Boundaries to Testing, Accessibility, Localisation and Publishing.
Swift, State and the iOS Runtime
value semantics · reference semantics · optionalFIT3178 starts from Swift because every later iOS feature depends on choices made at the language boundary. A value type normally gives independent copied state; a class gives shared identity; an optional makes absence part of the type.
- value semantics
- reference semantics
- optional
- reason from Swift values and object lifetimes to predictable interface behaviour
- Swift syntax is not an architecture; the relevant question is which object owns the state and how changes propagate.
Application Architecture, Navigation and Collections
model · view controller · reuse identifierArchitecture in FIT3178 is the arrangement of responsibilities that keeps screens comprehensible as an app grows. Start from the model: data and rules that still make sense without a particular button, label or controller.
- model
- view controller
- reuse identifier
- separate model state, view presentation and navigation so screens remain testable
- A visual hierarchy does not establish data ownership; navigation code must not become the only place where model changes are stored.
Data Persistence and Offline State
serialization · persistent store · migrationPersistence begins with a product question: which state must survive process termination, reinstall, device change or temporary disconnection?
- serialization
- persistent store
- migration
- choose persistence according to data shape, lifetime, consistency and failure cost
- Successful writing does not prove successful recovery; test termination, corruption, partial data and schema change.
Web Services, Concurrency and Firebase
request lifecycle · asynchronous task · cloud consistencyA web-service feature crosses five separate gates: the request must be constructed correctly, transport must complete, the response status must be acceptable, the payload must decode, and the result must still matter to the current screen.
- request lifecycle
- asynchronous task
- cloud consistency
- turn remote responses into validated local state while making latency and failure explicit
- A successful HTTP response is not proof of valid domain data, current screen relevance or durable cloud agreement.
Maps, Location and Privacy Boundaries
authorization state · coordinate · geofenceLocation-aware applications must work through permission and measurement, not around them. Authorization is a state that can be undetermined, denied, restricted, approximate or precise depending on platform controls.
- authorization state
- coordinate
- geofence
- use geospatial capabilities with explicit permission, accuracy and lifecycle controls
- Coordinates are measurements, not identities or intent; never treat permission once granted as permanent consent.
Media, Adaptive Layout, Sensors and Charts
adaptive layout · sensor sample · chart encodingMedia, layout, sensors and charts meet at the rendering budget. Images can be large, sensor streams can be frequent and charts can contain many marks.
- adaptive layout
- sensor sample
- chart encoding
- translate device inputs into accessible, stable and performance-aware presentation
- A visually polished chart or sensor trace does not establish valid measurement, accessible meaning or causal interpretation.
AI Features, Notifications and Deep Links
AI output · notification payload · deep linkAI assistance, notifications and deep links all deliver external suggestions to the app. Their sources differ, but the architectural question is similar: how does an untrusted input become a validated state transition?
- AI output
- notification payload
- deep link
- coordinate intelligent output, system delivery and navigation without bypassing consent or validation
- A route request or fluent generated suggestion is untrusted input; neither may bypass permission, existence checks or user review.
Testing, Accessibility, Localisation and Publishing
test seam · accessibility semantics · localisationRelease quality is a chain of observable behaviours. Testing controls dependencies so state transitions can be reproduced. Accessibility gives interface meaning beyond visual arrangement.
- test seam
- accessibility semantics
- localisation
- convert application quality into verifiable behaviours across users, locales and release states
- Passing a happy-path demonstration is not release evidence; quality must survive controlled failure, assistive use and locale change.
The schedule moves from Swift and application architecture through persistence, web services, Firebase, location, media, sensors, AI-supported features, notifications, testing, accessibility, localisation and publication. The chapters in this resource preserve that sequence while focusing on the decisions that connect the topics.
The portfolio structure changes how the course should be studied.
Accumulating pages of code or points is not the same as meeting every required pass task to standard. Each portfolio item should make the problem, state ownership, dependency boundary, implementation choice, test and reflection recoverable in an OnTrack discussion.
A student should be able to explain what changed, why the chosen boundary is defensible and what failure path was tested.
Swift fundamentals control later architecture. Value and reference semantics determine whether an edit is copied or shared. Optionals make absence part of the model. Closures and asynchronous work introduce lifetime.
The useful question is not whether a particular syntax can be recalled, but whether the student can trace the same state across user interaction, navigation, storage, a remote response and a late completion.
Application architecture separates domain meaning from screen lifecycle. Models carry stable identity and rules. Views present. Controllers or coordinators translate user intent and navigation.
Table and collection cells are reusable presentation objects, not durable records. When a collection changes, stable model identity must survive even though index paths and cells move.
Persistence and services extend the state boundary. Stored data may be absent, corrupt or created by an earlier schema. Network responses may be delayed, malformed or no longer relevant. Cloud listeners can conflict with local edits.
A robust app therefore distinguishes transport success from domain validity and distinguishes writing bytes from proving that meaningful state can be recovered.
Device capabilities introduce permission and measurement. Location is authorised at a changing scope and observed with error. Sensors provide time-stamped noisy samples. Media loading and chart rendering consume resources.
Adaptive layout, accessibility semantics and clear units turn those inputs into a usable decision rather than a technically impressive but brittle screen.
AI output, notifications and deep links are treated as external input. Each must be parsed, validated and routed through current application state. A fluent suggestion may be wrong; a notification may be stale; a link may target an object the user cannot access.
Safe handling keeps consent, identity, existence and review controls visible.
Testing, accessibility, localisation and publishing are not final decoration. Test seams control time, network and storage so behaviour can be reproduced. Accessibility communicates interface meaning beyond visual arrangement. Localisation challenges fixed width and assembled text.
Clean-install and release builds expose assumptions hidden by a developer's cached environment.
The eight chapters use original practice cases. They do not reproduce official portfolio prompts or solutions. Current dates, platform versions, submission settings and approved adjustments belong to the live Monash systems.
The local source manifest and official 2026 capture control offering and assessment claims.
A practical study loop has four parts: draw the state or dependency map; predict the result of one changed condition; implement or explain the boundary; verify the normal and failure paths. End by naming the evidence that would make the design unacceptable.
This produces compact, discussion-ready reasoning rather than a screen that works only in the recorded happy path.
Revision should alternate between code and explanation. First reconstruct a mechanism without the project open. Next inspect a small example and identify ownership. Then change permission, timing, identity, locale or failure. Finally articulate which layer should respond.
The same habit transfers from optional handling to cloud conflicts and from stale notifications to release tests.
The final quality question is consistent across the unit: can every user-visible result be traced to owned state, a validated dependency and a lifecycle that still applies?
If the answer depends on global access, permanent permission, fixed timing, a stable index path or a lucky network response, the design is not yet ready for competency evidence.
FIT3178 carries 6 credit points in the current Monash Handbook; live enrolment, platform and competency controls remain authoritative.
